Villain was a pretty decent LAG.
On the flop i probablly should've 3bet/fold, but i had trouble pressing the time bank button for some reason so instinctively i called. On the turn i decide to go broke, i see FDs in his range, maybe something like 79 along with sets and maybe K8.

It's fine like that really, if he's indeed a "pretty decent lag" chances are he's going to fire the turn again with all his draws, where you can get him to stack off with way less equity than he would have had on the flop. Meanwhile you can fold ugly turns easily unless you think he'd also play pure bluffs and/or worse Kx hands like that.
